John Sefton is incensed about the idea of a black hole, because he read 
somewhere that the central idea of a black hole is infinite gravity, and 
he will insist that gravity has to be finite (even though he believes 
the size of the universe is infinite). And because he believes this is 
the central lynchpin of black holes, then a belief in finite gravity 
means to him that black holes are denied.

But John is kinda missing the boat on what makes a black hole.

First of all, let's get straight what a black hole is. A black hole 
happens when a sufficiently large but FINITE amount of matter falls 
inside a sufficiently small but FINITE radius. This radius is called the 
Schwarzchild radius. That radius is r = 2GM/c^2. All you have to do is 
get more mass than M inside that radius r, and you will have a black 
hole. A black hole simply means that ANYTHING that falls inside this 
radius will never get out or send anything out. Things outside of this 
radius can be perfectly happy, orbiting around and never falling in. The 
idea of a black hole swallowing everything on the OUTSIDE of this radius 
is just bullshit, gradeschool bullshit. Some stuff will fall in, sure, 
just like some stuff falls into the sun, but the planets have not fallen 
into the sun for billions of years.

So far, there is absolutely nothing about infinite anything here.

So now the question is, why don't ALL stars compress under gravity and 
become black holes. The reason is that there are sources of outward 
pressure, obviously, and if the outward pressure equals the inward pull 
of gravity, then collapse doesn't proceed.

In ordinary burning stars, what provides the outward pressure is heat 
from nuclear fusion. Heat pushes matter outward, as anyone who has 
watched a firecracker knows. If gravity is enough to pull it in (more 
than a firecracker's gravity, for sure), then there can be a balance, 
which is like our sun.

When the fuel for fusion is gone, then there is no fusion to provide 
heat to push things outward, and the star starts to collapse, until a 
new outward force pushes it out. That outward force is almost exactly 
the same thing that makes a metal solid. It's called electron 
degeneracy, and it's basically the Pauli exclusion principle at work. 
Electrons in the same state cannot get too close to each other, because 
they are fermions. It's this repulsion, not from electrostatics, but 
from Fermi statistics and the Pauli principle, that makes metal solid, 
and it also makes burnt-out stars resist gravitational collapse.

But if you get enough gravitational pressure coming from the further 
collapse, then you can introduce something that only happens extremely 
rarely in solid materials, and that's the electron being squeezed into 
the nucleus for long enough periods of time that it interacts with a 
proton and generates a neutron. Do this enough, and all of the atoms 
collapse into the size of their nuclei, which is a trillion times 
smaller and more dense. Since there are equal numbers of protons and 
electrons, you're going to end up with something like a solid again, but 
now made up entirely of neutrons. The good news is that neutrons are 
also fermions, and the Pauli exclusion principle also applies to them, 
and so you can't just squeeze neutrons together forever, before they 
want to push each other away and you now have outward pressure. When 
that balances gravity, then you have a stable neutron star, of which 
we've seen plenty.

But if this neutron star collapse brings enough mass close enough 
together that you're inside the Schwarzchild radius, then gravity is 
strong enough to not be balanced by neutron degeneracy. So then another 
collapse happens just like the previous ones. The difference here is 
that we're not aware of any other layer of degeneracy pressure that 
might cause another balance with gravity. So AS FAR AS WE KNOW, there is 
nothing to stop the collapse from gravity and it is ASSUMED that it will 
just continue unstopped. However, as this all happens inside the 
Schwarzchild radius, we WILL NEVER KNOW anyway, because we can't see 
anything coming out to tell us what's going on.

All of this is to point out that infinite gravity is NOT a logical 
must-have for black-holes. All that is needed is enough FINITE gravity 
to overcome the FINITE neutron degeneracy pressure, and you'll have a 
black hole, and what happens inside after that is moot.

So John .... get over it. The crap comic book stuff you read about black 
holes is cheapo, sloppy, popularization nonsense.
